3 leds flashing,1200,800 and rinse hold and wont start.The book says motor fault.Sure enough carbons shot.Fitted carbons and comm was in good order,continuity on all motor circuits.Problem is it still wont start and leds still flashing.I see on your search you have to reset the board,have you got details of this process please? By the way i took the boards out and they dont look damaged,665351 and 449238,and the customer reports the house trip switch did not go at the time.
Cheers
Bob
